ICD-10 Code for Schizophrenia
The ICD-10-CM code for schizophrenia is F20.9 — Schizophrenia, unspecified. This is the code the Alphabetic Index gives for schizophrenia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
F20.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
